STEVAL-ISA095V1
Description
The STEVAL-ISA095V1 demonstration board is
designed to provide an evaluation platform for
testing the ST1S14, a step-down monolithic
power switching regulator capable of delivering up
to 3 A of output current. The high current level is
possible thanks to an HSOP8 package with
exposed frame.
The output voltage can be set from 1.22 V. An
internal oscillator fixes the switching frequency at
850 kHz.
A Power Good open collector output validates the
regulated output voltage as soon as it reaches the
regulated level.
Pulse-by-pulse current limiting offers effective
constant current short-circuit protection, while the
current foldback decreases overstress in
persistent short-circuit conditions.
